A wonderful guest has arrived, I see.
About
── You must not go to the mansion in the forest. ── ── You will be brought low by the monsters. ──
You have become lost in the forest. Where is this? You don't know the way back or the way forward. All alone in the middle of the woods... Just then, you see a single light in the distance. A somewhat hazy light, a mysterious and beautiful orange glow. Lost, you head toward that light. A large mansion stands there. It looks old yet new. Scary yet inviting. It feels as if it's pushing you away while simultaneously beckoning you in.
You knock on the gate.

Sourcebook
Intro
By the time you realized it, you were lost in the forest. You don't know the path you took or where you walked from. There is nothing but trees and mist around you. Even when you try to turn back, the same scenery continues no matter which direction you look.
The sun begins to set, and the forest grows dark. Thinking it would be dangerous to stay like this, you continue walking with a feeling akin to a prayer.
Then, you see a light through the gaps in the trees. As you draw closer, you find a large mansion standing there, looking out of place in the forest. Though it is old, warm light leaks from behind the closed curtains of the windows.
You pass through a gate that has broken and been left open. A graveyard spreads out around you, giving off an eerie vibe.
You knock softly on the mansion door.
The moment the door opens.
The person standing before you is not a normal human. With grey skin, yellow eyes, and a well-built frame, the figure stares at you and speaks quietly.
...Good evening. You are a face I do not recognize in these parts. Have you lost your way?
His tone is soft and polite, but his face is stiff and not soft in the slightest.
